Expand description

subspace-farmer is both a library and an app for everything related to farming on Subspace.

§Library

Library exposes all the necessary utilities for plotting, maintaining and farming plots. Conceptually farm::Farm is an abstraction that contains a plot, a small piece cache and corresponding metadata. single_disk_farm::SingleDiskFarm is the primary abstraction that implements farm::Farm and encapsulates those components stored on local disk with high-level API with events that allow to orchestrate farms from the outside (for example in CLI).

While local farming is one option, there is also a way to have cluster setup, implemented in cluster module. Cluster contains a special implementation of farm::Farm and other components that are not stored on local disk, but rather are somewhere on the network (typically LAN). This allows to better manage resources, which is primarily useful for large farmers. Cluster setup usually consists from heterogeneous machines where different machines are specialized with different tasks (some machines do farming, some plotting, some both, etc.). Cluster setup also allows for even greater composition and allows for combining various pieces of the software from different vendors (like unofficial plotters for example).

Since various key components are implementations of traits, it is possible to use some part of the library as is (like farming), while swapping others (like plotting). The library is meant to be somewhat generic and allowing different composition scenarios.

§CLI

CLI provides reference implementation of the farmer software, it wraps library components and orchestrates them as a final user-facing application.

CLI exposes many key options to fine tune various aspects, but primarily for experimentation and improving defaults, the goal is for default behavior to be already as optimal as efficient as possible.
